Question

If the load is between the fulcrum and the effort, the lever belongs to _____.

• A. Class I
• B. Class II
• C. Class III
• D. Both A and B

Answer 1

The correct option is B

Class II

An explanation for the correct option:

Option B: Class II

1. As we already know that a lever contains a rigid rod that can move freely around a fixed point called the fulcrum.
2. In a class II lever, the load is present between fulcrum and effort.
3. Therefore, option B is correct.

An explanation for the incorrect options:

Option A: Class I

1. The fulcrum is present between effort and load in a class I lever.
2. It works by changing the direction of the force. So option A is incorrect.

Option C: Class III

1. The effort is present between the fulcrum and the load in a class III lever.
2. So the effort arm will be smaller than the load arm. So option C is incorrect.

Option D: Both A and B

1. As option A is incorrect. So option A and B both can never be correct.
2. Therefore, option D is incorrect.
